TIL Test a branch using dep with golang

I just needed to test out a branch fix for a go package and discovered it’s pretty easy to do if you’re using dep for dependency management by specifying a new source for the package.

# Gopkg.toml

[[constraint]]
 name = "github.com/xenolf/lego"
 version = "2.0.1"

# change to test out a fix on a branch

[[constraint]]
 name = "github.com/xenolf/lego"
 branch = "fix/oscp"
 source = "https://github.com/ldez/lego"
